- Nickel Ore Processing Non Magnetic Product
The Nickel Disc is a product of the carbonyl refining process. This process makes one of the purest forms of nickel. The consistent product quality and the distinctive shape (for optimum handle-ability and convey-ability) make nickel discs an industry standard for a wide range of melting applications.

The olivine phase traps the existing nickel. This ultimately lead to increased levels and recovery of nickel in the metal products. The XRD analysis has proven the detection of forsterite phase ((Mg, Fe) 2 SiO 4) (00-034-0189) in non-magnetic slag on the three variables obtained. Figure 8 reveals the phases formed in the non-magnetic

The metallurgy of nickel is complicated in its details, many of which vary widely, according to the particular ore being processed. In general, the ore is transformed to dinickel trisulfide, Ni 2 S 3 (with nickel in the +3 oxidation state), which is roasted in air to give nickel oxide, NiO (+2 state), which is then reduced with carbon to obtain the metal.

Primary world nickel production in 2020 was 2430.7 kt Ni; 69% (1677.7 kt) of them came from oxidized nickel ores (laterites) and 31% from sulfides. Production-wise, 87.7% of the 1677.7 kt came from pyrometallurgical and 12.3% from hydrometallurgical processes. For a long time, Fe-Ni had a 20–40% Ni analysis, but in 2006 a new Fe-Ni quality came into …

It is one of the most widely used processes for extracting minerals like nickel from their ore – the natural rock or sediment that contains them. At the end of the flotation process, the nickel sulphides can be skimmed off and dried. Now at around 18% nickel, the concentrate is driven to Deception Bay, around 100km north of the mine.
